TECHNICAL FIELD

The subject matter of the present disclosure generally relates to medical dressings. More particularly, the subject matter of the present disclosure technically relates to medical dressings, such as bandages and compression bandages. Even more particularly, the subject matter of the present disclosure technically relates to medical dressings, such as bandages and compression bandages, requiring frequent monitoring and changing.

BACKGROUND

In the related art, bandages or dressings need routine changing during a post-surgery period, or a post-trauma period, for speedy healing and for reducing medical complications. Bandages typically need changing every few hours, or few days, depending on the condition of a wound. Current tracking of bandage changes in the related art is manual and depends on the physical examination thereof by nursing staff. This related art technique is imprecise and time consuming. Related art monitoring the condition of a wound, only occurring during a bandage change, is typically merely qualitative; and infections may not be noticed by the nursing staff until well into progression, thereby leading to further injury of the subject as well as possible medical malpractice.

In the related art, some monitoring devices include RFID tags and sensors have been applying them on a bandage for sensing humidity, for monitoring vital signs and temperature by way of a flexible bandage having a conductive ink, and for sensing pressure, via a strain gauge, temperature, and humidity, by way of a wound pad. Also in the related art, a wireless diagnostic tool, having a semiconductor chip disposed under a bandage, has been used for monitoring changes in bandage pressure, moisture level, and local temperature at the wound site.

Accordingly, challenges experienced in the related art include a limited use of RFID tags with humidity sensing technology, humidity sensing techniques that use capacitive effects or resistive effects, sensing techniques for less useful characteristics, sensing techniques for detailed pressure information with only scant sensing of moisture information, sensing techniques for testing parameters of pressure, moisture, and temperature, of a surrounding atmosphere. These related art techniques are not suitable for specific robust use in relation to wound care.

BRIEF SUMMARY

The present disclosure addresses at least many of the foregoing challenges experienced by related art wound care techniques, by way of a dressing apparatus, such as medical dressing, e.g., at least one of a bandage and a compression bandage, comprising radio-frequency identification (RFID) tags for both providing a change-alert and reporting specific wound conditions.

The dressing apparatus of the present disclosure involves an electrically conductive element configured to fully sense a plurality of parameters, such as detailed pressure information, detailed moisture information, and detailed temperature information by way of conductive thread sensing.

In accordance with an embodiment of the present disclosure, a dressing apparatus for facilitating healing comprises: a dressing member; an electromagnetically conductive element mechanically coupled with the dressing member; and a primary RFID device configured to transmit at least one output signal to the electromagnetically conductive element, to receive at least one return signal from the electromagnetically conductive element, and to provide an alert if the at least one return signal has a strength corresponding to at least approximately a threshold amount of fluid present in the dressing member, whereby healing is facilitated.
